Tank Installation
• Install oil tank and piping in accordance with National
Board of Fire Underwriters and local regulations.
• Oil storage tank, vent,
fi
ll pipe and caps should be as
prescribed by local codes.
• In no case should vent pipe be smaller than 1¼" I.P.S.
Fill pipe should not be less than 2" I.P.S.
Suction Line Installation
• Suction line from tank to burner should be one
continuous piece of tubing to prevent air entering line.
• Suction line, must be
⅜
" O.D. copper tubing for runs of
50 feet or less, and ½" O.D. for longer runs.
Oil Line Installation
• Oil return line, same size as suction line, must be used
on any installation where bottom of tank is below fuel
unit of burner.
• Bury oil lines or protect from mechanical injury.
• Flare
fi
ttings on all oil lines are recommended.
Compression
fi
ttings on suction line often allow air to
be drawn into fuel pump, making it dif
fi
cult to maintain
oil pressure at nozzle.
• Do not run overhead fuel lines from tank to oil burner.
Fuel Pump Connections
• Fuel pump connections and by-pass should be made
according to instructions attached to fuel pump.
• If tank is more than 20' from boiler, install two stage
fuel unit in place of single stage pump supplied as
standard equipment with burner.
• Verify rotation and speed are the same and pump is
suitable for burner horsepower rating.
Install oil line
fi
lter and shut-off valve in the suction line.
Install shut-off valves in both suction and return lines at
the burner for convenience in servicing burner.
Allow extra tubing at burner so burner may be removed
from boiler for cleaning without disconnecting tubing. An
optional
fl
exible oil line is available. See
